Sequence of M87 Images. MPEG This sequence begins with an optical view of M87, a giant elliptical galaxy only 50 million light years away in the Virgo cluster. X-ray data (red) are then overlaid and reveal a series of loops and bubbles in the hot gas that surrounds the galaxy and fills the cluster. These are evidence of repeated outbursts from close to the supermassive black hole in M87, which are responsible for producing sound throughout the cluster.
